The five elements of high yield cultivation of straw mushroom

I. Arrange production season reasonably

Straw mushroom is a high-temperature edible mushroom. In order to allow the mushroom to germinate normally after sowing, the cultivation season should be performed at a daily average temperature of 25°C or more. This is conducive to the growth of mycelium and the development of fruit bodies, plastic greenhouses can be planted in advance to mid-May, greenhouse mushroom house can be cultivated throughout the year.

Second, choose a favorable cultivation place

The straw mushroom can be cultivated both indoors and outdoors, but it is more advantageous to cultivate it outdoors. When cultivated outdoors, fertile, loose, breathable, and convenient irrigation and drainage farmland should be selected. For example, rapeseeds, watermelons, and other places are the most suitable for cultivation. The yield of raw wild land is far lower than that of sage. Before weeding, weeds should be removed, and we should open the trunking ditch.

Third, strictly select and handle culture materials

Whichever raw material is selected, it should be dry and free of mildew and exposed for 2-3 days before production. The newly harvested straw must be completely dry, otherwise it will fail easily. Pre-wetting with 5% lime water before sowing, pH value of 12 or more, and then build a heap fermentation 4-5 days, culture medium moisture content reached 65-70%.

Fourth, select good strains

If the seeding rate is increased, genetic genes of the strains in production are of crucial importance. The selection of high-quality, high-yield strains can significantly increase yield. Such as Guangdong's V23, V5, V17 and other high-quality strains.

V. Adopting scientific cultivation management techniques

The “two-stage cultivation method” that uses Batu disinfection, bagging and sterilizing, and then unpacking small plastic sheds or plastic sheds with plastic coverings can significantly increase production. The first method of this method is to make the raw material of rice stalks compacted and compact, and the raw materials are closely connected, which is beneficial to germs, and the drawbacks of loosening the grass and damaging the mushroom buds and edodes of mushrooms due to the looseness of the raw materials during the harvest are avoided; During the germination stage, the balance of the temperature of the material can be adjusted by subtracting the number of piles from the stack to promote the normal growth of the mycelium. The third is to improve the microclimate environment and physical structure within the mushrooming yard by covering the soil so that the fruit body of the mushroom can be formed from the primordium. The growth and development are always in a relatively stable environment, less interference by external factors, which is beneficial to increase the yield; Fourth, the nutrients in the soil can be fully utilized after covering the soil, especially through the penetration and transport of soil moisture content. Satisfy the growth of the water requirement of straw mushroom, so as to achieve the purpose of high quality and high yield.

When the straw mushroom covers the soil, the bag should be laid flat, with a distance of 5-10 cm between the bags, gap fill, and 1.5-2.0 cm of the topsoil. After the soil is covered, the water should be poured in enough time so that the hyphae in the material can fully utilize the soil moisture for the mushroom growth. In water management, one should not avoid replenishing water when the entity is formed. Second, avoid directly adding tap water or groundwater to avoid causing large temperature differences and batches of dead mushrooms.
